SDWebImage 載入Https自簽名證書時的圖片問題
摘要：
你是否遇到了這種情況，好不容易把自簽名HTTPS證書配置好了，訪問https介面也成功了，但是圖片載入不出來？
傳了SDWebImageAllowInvalidSSLCertificates 還是沒效果沒效果（這種情況只適用於CA我覺得），

你是否遇到了這種情況，好不容易把自簽名HTTPS證書配置好了，訪問https介面也成功了，但是圖片載入不出來？
傳了SDWebImageAllowInvalidSSLCertificates 還是沒效果沒效果（這種情況只適用於CA我覺得），
並且一直 HTTP load failed (error code: -999 [1:89])，
經過不懈努力，終於找到了在不修改SDWebimageDownloader.m原始碼的情況下的解決方案；
通過建立SDWebimageDownloader的分類來實現，如下：
.h 檔案 1 #import "SDWebImageDownloader.h" 2 3 @interface SDWebImageDownloader (AFNHttps) 4 5 @end
1 #import <SDWebImageDownloader.h>
2 #import "SDWebImageDownloader+AFNHttps.h"
3
4 @implementation SDWebImageDownloader (AFNHttps)
5
6 + (void)load {
//設定SDWebImageDownloader的證書
7[SDWebImageDownloader sharedDownloader].urlCredential = [self myUrlCredential];
8 }
9
10 + (NSURLCredential *)myUrlCredential {
11
12NSString *thePath = [[NSBundle mainBundle] pathForResource:@"p12證書名" ofType:@"p12"];
13//倒入證書NSLog(@"thePath===========%@",thePath);
14NSData *PKCS12Data = [[NSData alloc] initWithContentsOfFile:thePath];
15CFDataRef inPKCS12Data = (__bridge CFDataRef)PKCS12Data;
16
17SecIdentityRef identity = NULL;
18// extract the ideneity from the certificate
19[self mosM_extractIdentity:inPKCS12Data toIdentity:&identity];
20
21SecCertificateRef certificate = NULL;
22SecIdentityCopyCertificate (identity, &certificate);
27
28return [NSURLCredential credentialWithIdentity:identity certificates:nil persistence:NSURLCredentialPersistencePermanent];;
29 }
30
31
32 + (OSStatus)extractIdentity:(CFDataRef)inP12Data toIdentity:(SecIdentityRef*)identity {
33OSStatus securityError = errSecSuccess;
34CFStringRef password = CFSTR("p12證書密碼");
35const void *keys[] = { kSecImportExportPassphrase };
36const void *values[] = { password };
37CFDictionaryRef options = CFDictionaryCreate(NULL, keys, values, 1, NULL, NULL);
38CFArrayRef items = CFArrayCreate(NULL, 0, 0, NULL);
39securityError = SecPKCS12Import(inP12Data, options, &items);
40if (securityError == 0)
41{
42CFDictionaryRef ident = CFArrayGetValueAtIndex(items,0);
43const void *tempIdentity = NULL;
44tempIdentity = CFDictionaryGetValue(ident, kSecImportItemIdentity);
45*identity = (SecIdentityRef)tempIdentity;
46}
47if (options) {
48CFRelease(options);
49}
50return securityError;
51 }
